CT or Computed Axial Tomography, sometimes called a CAT scan, is a painless medical test that helps doctors diagnose and treat medical conditions. CT imaging uses special X-ray equipment to produce multiple images or pictures of the inside of the body. A computer takes these pictures and joins them together to create cross-sectional views of the area being studied. CT scans of organs, bone, soft tissue, and blood vessels provide greater clarity when compared to an X-ray exam. The result is a very detailed view of the body.
